Just a bulge without herniation is not much. You really dont need to worry about going for an MRI
. You can consult a good physiotherapist for proper exercises to strengthen your back muscles and proper posture while seating. Low backache
is a common problem and nothing very drastic is required. You may take local painkiller sprays like volini
spray is the pain is very severe
Hope this helps
